5.5
Operating mode: Slave mode
In this operating mode the bus controller CPC10 is involved in a PROFIBUS-DP system. Communication to the
bus controller CPC10 works faultlessly and the controller can be addressed and controlled by the superordinate
control unit.
The behaviour of the bus controller with simultaneous use of a field bus interface and the USB service and
maintenance interface can be determined by means of the configuration of the device in the superordinate
control unit. It can be pre-selected there that the USB service and maintenance interface is granted either
only reader access or reader and editor access. In the event of editor access, changes of the parameterisation
of the electronic circuit protectors can be carried out in parameter selection to the field bus system. These
parameter changes will then be advised to the superordinate control system and can be adopted by it or also
overwritten. The user can select the behaviour accordingly.
5.6
Operating mode: Firmware update mode
The devices are supplied with a software programmed according to their functionality. If the functions of the
devices are extended, this will be carried out in the firmware. It is therefore necessary to carry out a firmware
update if the new functionality shall be used. More detailed information regarding the firmware update are
made available in the user manual of the software
ControlPlex®
Views.
